To all whom 'it may concern:

Be it known that I, JAMES F. CRAVEN, a

resident of Pittsburg, in the county of Alle-A ing Semisolid and Pasty Substances, (Case f 8,) of which the following is a specification. This invention relates to receptacles f or containing, storing, transporting and `d1s charging' semi-solid and pasty substances.

The device is intended morel particularly cups of machines, and the particular purpose is to enable the grease to be supplied to bearings without liability of dirt 'or grit entering the bearings with the grease, and also. smearing up .or soiling the machinery or hands of the user. i The invention, however, is not limited to this particular use, but is adapted for putting upA in a substantially sealed conditionl any semi-solid Vor pasty substance, such as vaseline, cold cream, and

the like, or even butter or lard, and-delivering the same from. the ontainerinany desired quantity or quanti ies. The particular purpose of ,the present 1n,-

vention is to provide a device'for the purpose specified so constructed that it auto# matically .closes the outlet orifice when the operation of discharging-.the substance ceases.`

Theinvention comprises 'the construction and 'arrangement of parts hereinafter described and claimed. In the accompanying drawing Figure 1. is 'a vertical section' through one form of the device showing 'l the outlet orice closed;

Fig.' 2 is a'plan view o f'the same;- and Fig? 3 is a .vertical section showing a modilica- "tion.`

. The receptacle itself may be of-any desiredv shape or size,` and may be. constructed orbuilt up in any desired way and from any desired material.V As shownin the drawin sv the receptacle is formed as a. substantial y cylindrical tube 1 which .may be of sheet metal or other thin substance 'and is shownl as formed from paste or paper board.VV One end oithis receptacle is closed by means of a head 2L which isshown. crim ed onto. thev tube 1. AThis can be done after t receptacle isilled, but if desired the head 2 can be secured to the tube -1 in any easily removable leather 7 to form a tight fit the receptacle and being longitudinally movable therein. Various devices may bensed for moving the piston. longitudinally, 'that shown compris. ing a threaded rod 8 arranged centrally of the-receptacle and engaging a.- threaded opening in the piston or' follower and at'its outer` Vend secured to a'c'ap ,.9 which is rotatably.

but longitudinally immovable on the outer.

end of the tube 1, such as by turning its'edge .overa flange or shoulder 10v on'the'tube 1 or on a col1ar llcrimped onto said tube. -This cap is provided with a knurled or milled peripheral portion 12 by means of which vit can be readily rotated.' It serves notvonly as 'a means for rotating the screwS,

but 'also as a closure for the outer end of the l receptacle. The piston 6 is prevented from rotating by vmeans of a longitudinal in- -wa'rdly projecting rib 1 in the tube 1 which engages a grooveinthe piston. In the case l of apaper tubel such riby can beformed by -means .of a 'paste board strip pasted to the inner face ofthe tube.` kIn case of a sheet metal', tube the usual crimped seanr forms such inward longitudinal rib.

Obviously when the cap 9 is rotated while 4 thebody 1-'is'heldstationary the piston fis' caused to move toward the discharge orifice i and forces the substance'out ofthe latter. g

- The automatic. means for openingand.

closing the discharge oriflce'comprises a suitable spring controlled valve. As'shown in Figs. 1 and 2 e. outlet oriice-13 is formed in4 a hood14wh ch can be pressed outwardl fromtheheadQ but preferably 'is a separa piece: soldered or otherwise' secured tothe head 2.. "rhehood 14 is'subSantia11y'-semi l cylindrical in cross, section, and. mounted thereon upona pinv orf-other` center 15 is a' segment shaped valve 16, one edge of which is engaged by a spring 17 which normally holds the valve in the position shown in Fig.

1 to close the outlet orifice 13. When, however, the piston 6 'is moved the pressure exerted on the material causes the latter' to enter the space 18 in thehood 14 and act against the exposed face of valve 16, thereby rotating said valve on its center against the tension of spring 17 and forcing the valve backwardly so as to uncover the discharge orifice 13. The valve will' remain Y open as long as the pressure on the material overcomes the force of spring 17. When the rotation of the screw 8 is stopped and the piston ceases to move the pressure of the material soon relieves itself'through the outlet orifice, and the spring 17 then rotates valve 16- in the reverse direction and closes the outlet orifice. 1f desired, the cap 9 may be slightly rotated backwardly after the necessary amount of material has -been discharged, to immediately relieve pressure and permit the spring 17 to close valve 16.

The rear face of the valve 16 is protected from the pressure of the material in the receptacle by the head 2, a. portion 18 of whichv is turned up in front of the valve and prevents the material getting Ybehind the valve. The spring 17 can be secured in any suitable way. As shown it is held between the valve and the cap 2 and endwise movement thereof is prevented by abuttin against a lip 19 on the upturnedpart 18 o the head 2. To prevent the valve being pushed too far by spring 17, said valve is provided with a lug 20 projecting into the outlet orifice and adapted to contact with one edge Wall thereof to stopthe valve. The opposite edge wall of the orifice is provided with a slot 21 to receive said lugand permit the oriiceto be -opened to itsfull extent.

Fig. 3 illustrates 'a modification in which the valve is formed of a spring band 24 secured to the inner face of the hood 14 and havinga straight or flat portion 25 covering the outlet or'tice 13, and an inclined 'portion 26 leading down to -the -opening 5 through the head 2. l In this case the hood 14 1s preferably rectangular in cross section instead of semi-cylindrical, but inany event the .spring 24 will be off a corresponding back to norma tentsA are shielded from dirt or from odors of I other substances stored in the same vicinity. The contents can be readily discharged therefrom in any desired quantity and without danger of soiling the hands. The packagehas no projecting portions, so that it can be conveniently and,` safely packed, shipped and stored. i

What I claim is: y
